Re: RNG150N Lan Light

There’s no internet connection out of the cable box. Why would you connect your computer to the cable box and not a modem

We don't know why their TV boxes have an Ethernet port. Maybe it's used in manufacturing or testing, or maybe Comcast uses it to set up the boxes, or maybe they just included one in case they needed it someday. Only an insider at Comcast or one of the manufacturers could say for sure, and to my knowledge none ever has.

All we know is the port connects to a DHCP server that assigns a private IP address in the 192.168.x.y range but provides no access to anything.

It may have detected another cable box, either in your home or even a neighbor. You may want to have a MoCA filter added.

To check if that is the reason:

Press MENU twice to get to the main menu.

Select "Setup"

Select "Cable Box Setup"

Scroll down to the Configuration entry and hit OK.

On the device configuration screen, press the FAV button to enter the iGuide diagnostics.

Press FAV a few times until you get to a screen title "Software FIltering 1". Look for an entry near the lower-right titled "HMA Enabled". If it says "Yes", then your box has detected another box and is trying to communicate with it.

If you press FAV a few more times, you come to a "Multi-Room DVR" screen. If it has data, it again means it found something.

This is what the screens should normally look like, with no other device detected:
